Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid, known as "industrial blood". The upper part of the crust has oil storage. The main component is a mixture of various alkanes, cycloalkanes and aromatics. The oil formation mechanism of petroleum has two theories of biological deposition and oil change and petrochemical oil, the former is widely accepted, and the petroleum is formed by the long evolution of organisms in ancient oceans or lakes, belongs to biological deposition and oil change and cannot be regenerated; the latter considers that oil is produced from the carbon in the earth's crust itself, is biologically unrelated and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material of many chemical industry products, such as solution, fertilizer, pesticide, plastics and the like, and generally, an internal pressure detection device is required on a petroleum pipeline to detect whether the pipeline has a leakage condition.
